GTA5 in Spring?

Computer and Video Games reports a indication that Grand Theft Auto V will be released in Spring 2013, saying this was found on some allegedly leaked posters on gta-five.pl, a Polish website that currently seems completely blank. They do reproduce the images, and we'll trust their super vision when they say "suggest - in very small print - the eagerly anticipated sequel will be available between March and May next year," adding "this has not been officially confirmed by Rockstar Games or Take-Two Interactive."
